Case Type   : 兼容M*数据库utc_date函数
Case Name   : UTC_DATE函数有括号及无括号测试
Create At   : 2022.11.25
Owner       : z@wan005
Description :
    1、建mot表
    2、使用utc_date函数查询当前的UTC日期，函数加括号
    3、使用utc_date函数查询当前的UTC日期，函数不加括号
    4、清理环境
Expect      :
    1、成功
    2、成功
    3、成功
    4、成功
History     :modified by z@wan005,2023.02.13，默认时区时间比utc时区时间快8个小时，
            因CI执行时间为早上6点，导致默认时区日期和utc日期不在同一天，导致断言失败，修改断言
